Well it took about 3 months for her to get completely cured. She had to follow a very strict diet based on what she CAN'T eat: beans, milk, dairy products (like cheese), spicy foods, some veggies like lettuce, cabbage, cauliflower, broccoli; some fruits like melon, banana, mango & the citric ones (orange, lemon, grapefruit). She can't eat CHOCOLATE (her favorite snack), chew bubble gum & drink sodas either!
As you can see, she couldn't eat for that time what she usually eats just like you. And the 2nd part of the problem is the "sensation" in the stomach that bugs her while she was sick; according to the Doctor, it happens because the stomach is a very sensitive area full of nerves that are very affected by such bacterias. Hence, the doctor prescribed her a special medication to rebuild & protect the stomach, along with some vitamins.
That was the way my Mom got better: with diet and medication.
P.S. Now is New Year here in Venezuela; following a family tradition, we are eating lentils ( a seed similar to the green beans) making wishes for $$$$$$. ha ha ha!
